3300 XL 50mm Proximity Transducer System Product DatasheetBently Nevada* Asset Condition MonitoringDescriptionThe 3300 XL 50 mm Transducer System consists of a separate 50mm probe, an extension cable, and a 3300 XL 50 mm Proximitor*Sensor. The large diameter coil gives this system a maximum linearrange of 27.9 mm (1100 mils), the longest linear range of our eddycurrent transducer line. This linear range makes the 3300 XL 50mmTransducer System ideal for measuring the differential expansion(DE) or rotor expansion (RX) of large steam turbine generators thatresults from the difference in growth rates between the turbinerotor and the machine stator (casing).Measuring Differential ExpansionThe Differential Expansion measurement is made by using twoproximity transducers that observe a collar or ramp some distancefrom the thrust bearing. Typical transducer mounting arrangementsthat require the 3300 XL 50 mm Transducer’s long linear rangeinclude:•Two transducers observing the same side of a collar.•Two complementary input transducers observing oppositesides of a collar, effectively doubling the measurable DErange.The criteria for selecting a mounting method are the size of theavailable target, the expected amount of rotor axial movement, andthe type of DE target that exists in the machine. If the collar height issufficient and the required total measurement range is less than27.9 mm (1.1 inches), the preferred configuration for redundantmeasurements is to use two transducers observing the same side ofa collar. When 28 mm to 56 mm (1.1 to 2.2 inches) of total range arerequired, install the transducers in a complementary fashion onopposite sides of the differential expansion collar or other targetmaterial.System CompatibilityThe 3300 XL 50 mm probe comes in three case & threadconfigurations to physically replace all standard 7200 50 mmsystems (including side and rear exit probes). The standard 7200style mounting brackets are still available as accessories. Inaddition, a new bracket to adapt the probe to the 50mm DE Integraltransducer sliding mount base is also available. The ProximitorSensor has a 0.394 V/mm (10 mV/mil) output that is identical to thatof the 7200 and 50 mm DE Integral systems, which allows customersto upgrade without requiring any changes in the monitorconfiguration. When upgrading from previous systems, everytransducer system component (probe, extension cable, andPart Number: 174014Rev: FProximitor Sensor) must be replaced with 3300 XL 50 mm components.Proximity Probe and Extension CableThe 3300 XL 50 mm probe is designed to survive the harshest steam turbine DE environments. It can continually operate and maintain its accuracy in high temperatures up to 200 ︒C (392 ︒F), and can withstand intermittent high temperatures up to 250 ︒C (482 ︒F). The 50 mm probe has both a front and rear seal which, combined with the High Temperature FluidLoc* cable (standard on all 50 mm probes), prevent moisture from entering the probe tip. Special high-temperature ClickLoc* connectors are also standard on the probe and extension cable. Each probe and cable comes with connector protectors and a disposable connector protector installation tool to ensure that the connectors remain free of contamination. The ClickLoc connector on the probe lead features a removable collar that facilitates routing the cable through tight clearances.The 3300 XL 50 mm probe is available in straight exit case styles with ½-20 English threads or M14x1.5 metric threads, including a locknut with predrilled safety wire holes. The side exit probe has two ¼-20 mounting holes in the rear of the probe case. For both straight exit and side exit probes the overall case diameter is 1.99 inches.Proximitor SensorThe 3300 XL 50 mm Proximitor Sensor1 has the same advanced features as all 3300 XL Proximitor Sensors. Its thin design allows it to be mounted in either a high-density DIN-rail installation or a more traditional panel mount configuration. Improved RFI/EMI immunity allows the 3300 XL Proximitor Sensor to achieve European CE mark approvals without any special mounting considerations. This RFI immunity prevents the transducer system from being adversely affected by nearby high frequency radio signals. SpringLoc terminal strips on the Proximitor Sensor require no special installation tools and facilitate faster, highly robust field wiring connections.Notes:Proximitor Sensors are supplied by default from the factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request. Mounting AccessoriesThe correct operation of the transducer system must be initially verified during installation and periodically thereafter. This is done by physically moving the transducer to simulate the motion of the shaft collar. This requires a mounting bracket that allows the transducer system to slide relative to the shaft rotor and collar.An optional Sliding Bracket can be ordered for the 3300 XL 50 mm Transducer for both single transducer and complementary input applications. This mounting bracket allows you to verify the transducer system and gap the probes by sliding the transducer system through its linear range. The base plate of the sliding bracket is installed on the inner surface of the turbine case near the differential expansion collar. Probes are installed in the probe clamp that attaches to the sliding carriage. The sliding carriage slides onto and is secured to the base plate with bolts and safety wire. To verify and install the transducer, loosen the bolts securing the sliding carriage to the base plate and move the sliding carriage and probes. A verification kit with spindle micrometer can be temporarily secured to the base plate to provide a reference for axial verification measurements. The spindle micrometer measures the movement of the transducer system relative to the collar during these verification tests. SpecificationsUnless otherwise noted, the following specifications are for a 3300 XL 50 mm Proximitor Sensor, extension cable and probe between 0︒C and +45︒C (+32︒F to +113︒F), with a -24 Vdc power supply, a 10 kΩ load, a Bently Nevada supplied AISI 4140 steel target that is 102 mm (4.0 in) diameter or larger. The system accuracy and interchangeability specifications do not apply when using a transducer system calibrated to any target other than a Bently Nevada AISI 4140 steel target.ElectricalProximitorSensor InputAccepts one non-contacting 3300XL 50 mm Proximity Probe andExtension Cable.PowerRequires -17.5 Vdc to -26 Vdcwithout barriers at 12 mAmaximum consumption, -23 Vdcto -26 Vdc with barriers.Operation at a more positivevoltage than -23.5 Vdc can resultin reduced linear range.Outputresistance50Extension cablecapacitance:69.9 pF/m (21.3 pF/ft) typical Field wiring:0.2 to 1.5 mm2(16 to 24 AWG)Recommend using three-conductor shielded triad cable.

DescriptionAccessories contribute to a reliable transducer system. Installing proximity probes during outages usually requiresone or more mounting accessories to help simplify the task.3300XL Transducer AccessoriesDatasheetBently Nevada Machinery Condition Monitoring145668Rev.HThese accessories allow you to quickly and efficiently install proximity probes and route the associated cables out of the machine case. These parts also help shield the cables from electrical noise and adverse environmental conditions. Having the proper mounting hardware on-site during the probe installation saves time and money for those responsible for the project.Junction boxesJunction boxes are normally mounted on or near the exterior of a machine case and enclose electrical connections in weatherproof or explosion-proof environments. Sealtite™ flexible conduit Flexible conduit routes probe cables safely to the sensor housing and then back to the monitors. The conduit protects transducer wiring from damage that splashing liquids or accidental contact with other equipment can cause.Sealtite flexible conduit consists of a galvanized steel core with an extruded thermoplastic cover. Pipe fittings are made of steel with a zinc-plated, chromate finish and are compatible with fittings found on our watertight equipment enclosuresProbe mounting bracketsProbe mounting brackets attach internally mounted proximity probes to the machine case. S upplied mounting bolts attach the bracket to the bearing or other location inside the machine casing. The bracket holds the probe and allows for adjustment of the probe tip relative to the observed surface.For most installations, use the standard 137492 non-clamping aluminum probe bracket. When using the 137491 brackets for 3/8-inch diameter smooth case probes, tightening the bolts will compress the probe hole around the probe and lock the probe into its preset gapped position. If your application requires additional electrical isolation from the mounting location (as in some generator and electric motor bearing locations), use the 27474 phenolic probe bracket. These mounting brackets are compatible with our 3300 and 3300 XL proximity probe systems, including 5 mm, 8 mm and NSv™ probes.To ensure that the brackets screws remain fastened within the machine, secure the screws with safety wire. Each mounting bracket includes special screws with holes drilled for safety wire.Cable SealThe optional 10076 Cable Seal is mainly for use in cable routing applications. It restrains the coaxial cable from movement, prevents abrasion, and provides splash protection. One end of the cable seal has a 1/4-18 NPT thread that allows you to thread it into a 4190-36 Adapter.The cable seal has an aluminum body and an oil-resistant, slit grommet so that you can install it over armored or non-armored cable without removing the connectors. AdapterThe optional 4190 Adapter attaches a junction box to the machine case. It also allows mounting of the proximity probe in some instances.The adapter offers a variety of threads and configurations. A dapter threads and configurations that are not listed in this data sheet may be available. P lease contact your sales representative for more information. Explosion-proof fittingsExplosion-proof fittings provide seals for housings in Division 1 and in Zone 0 and 1 hazardous areas. The fittings include sealing compound, packing fiber, and the appropriate adapter. Fitting kits are available. Refer to Explosion-Proof Fittings on page 6 for details and part numbers.Low-pressure cable sealThe 43501 Low-Pressure Cable Seal provides egress for up to 4 75Ω and/or 95Ω 3300XL, 3300 and 7200 cables, or up to 2 25mm DE or 50mmDE transducer cables, through a single hole in a machine case or other barrier.The cable seal is constructed of 303 stainless steel and a molded silicon rubber grommet and prevents leakage of fluids along the outer jacket of the cable. The seal has threads on both ends and fits into a tapped hole on the machine case or barrier. External pipe threads enable the seal to mate to conduit or housings. You can use the low-pressure cable seal only with non-armored cables. Its design seals pressures up to 345 kPa (50 psi) when properly installed.High-Temperature Cable TiesThe 173873 high-temperature cable tie is an economical alternative to metal brackets in high-temperature applications. These cable ties are molded from VICTREX® PEEK™ polymer for multiple uses in extreme environments up to +180°C (+356°F).SpecificationsJunction BoxesCylindrical Junction Box P/N 03818016 ComponentsMain body and blankcoverDimensionsOverall Height76 mm (3.0 in)Body Diameter89 mm (3.5 in)Hub-to-Hub121 mm (4.75 in) Base to Hub Center16 mm (0.64 in) Fittings3/4-14 NPT5 placesMaterial AluminumOptional Extension for 03818016 P/N 03818022ComponentsMain body Dimensions (Extensiononly)Overall Height93mm (3.7 in)Body Diameter90mm (3.6 in)Hub-to-Hub (flats)91 mm (3.6 in)Total ExtendedHeight150 mm (5.90 in) Material Aluminum Rectangular Junction Box P/N 03818065 ComponentsMain body and cover Dimensions Overall Height27.9 mm (1.10 in) Width of Body38.1 mm (1.50 in) Length of Body95.3 mm (3.75 in) Fittings1/2-14 NPT2 places Material Aluminum Rectangular Junction Box P/N 03818066 ComponentsMain body and cover Dimensions Overall Height61.0 mm (2.40 in) Width of Body44.5 mm (1.75 in) Length of Body102 mm (4.00 in) Fittings3/4-14 NPT2 places Material Aluminum Sealtite Flexible Conduit Components Refer to Figure 4.Fitting Options1/2-14 NPT3/4-14 NPTLength As ordered BracketsClamp Mounting Bracket for 3/8-inch diameter smooth body probesDimensions Refer to Figure 5.Mounting Screw Thread Size Options 10-24 UNC-2A M5 x 0.8-6gMaterial AluminumNon-Clamping Mounting Bracket for threaded case probesDimensions Refer to Figure 6.

● 电涡流位移传感器长期工作可靠性好、灵敏度高、抗干扰能力强、非接触测量、响应速度快、不受油水等介质的影响,常被用于实时监测,可以分析出设备的工作状况和故障原因,有效地对设备进行保护及进行预测性维修。

● 从转子动力学、轴承学的理论上分析,大型旋转机械的运行状态主要取决于其核心——转轴,而电涡流位移传感器能直接测量转轴的状态,测量结果可靠、可信。

过去,对于机械的振动测量采用加速度传感器或速度传感器,通过测量机壳振动,间接地测量转轴振动,测量结果的可信度不高。

3500监测系统的作用
4、键相传感器 电涡流传感器可以用来有效得提供基准相位信息。键相传感器的典型安装是将其探头呈放射状安装在转子周围,当转轴每次旋转时,就可以感知轴上设计特征信息(键槽等)。键相传感器可以创建一个基准信号用于测量绝对相位信息及确定机器的转速。 前置器系统被安装好之后,将观测到大轴上的“凹槽”或“突出”的地方会比正常的振动或距离测量产生明显的电压变化。这种明显的差别使得3500监测系统将每转一周产生的有用的信号与背景的噪音信号或振动信号区分开来。键相位信号在机组故障诊断中非常有用。
